Embodiment

[0009] The selected variety is Siyou No. 3, sown on April 20, 2008, and planted on May 25. The average row spacing is 60cm, the width of the row is 70cm, and the narrow row is 50cm. Triangular planting is used for ventilation and light transmission. At the beginning of flowering (about 10% flowering) on ​​July 10, surround the main stem with 8-12 cm long No. 24 thin iron wire on the main stem about 30 cm above the ground at the lower end of the first fruiting branch, and twist it tightly so that it is embedded in the epidermis of the main stem. The phloem gradually forms a nodular callus, which limits the excessive transport of organic matter to the root, and is suitable for tightness.

[0010] Field management was carried out according to conventional fertilizer and water management methods. Wipe out superfluous buds and remove leaf branches in mid-to-late June, pick tops and fruit branch tips in early August to prevent nutrient consumption, and pluck old leaves in mid-to-lat...

Abstract

The invention discloses a cotton ring embedded high-yielding culturing technology. In an early flowering period of cotton, ring embedding is carried out on a main stem of a lower end of a first fruit branch 30 cm away from the ground by a 24# fine iron wires with the length of 8-12 cm to reach phloem to gradually form nodular callus to limit organic nutrients to be excessively transmitted to a root; measures of cutting fruitless sprouts, pinching and picking up fruit branches are combined to promote nutrients to be transmitted to cotton buds and bolls so as to reduce the consumption of the organic nutrients, promote the growth of the cotton buds and the bolls, reduce the frequency of dropping and increasing the number of boll setting and the weight of bolls, and improve the yield of cotton. The cotton ring embedded technology has simple method, low cost, easy promotion and obvious effect of increasing production.

Description

Technical field: [0001] The invention relates to a high-yield cultivation technology of cotton ring embedding, which belongs to the field of agricultural cotton cultivation. technical background: [0002] The problem of bud shedding in cotton production is one of the difficult problems that cannot be well solved at present. The bud shedding rate is still about 50% in production, and the highest reaches 70%, which seriously inhibits the improvement of cotton yield. [0003] External factors that cause cotton buds to fall off include drought, insufficient light, disease and insect pests, strong wind or flowering and rain affecting the fertilization of embryos, etc.; nutritional imbalance between vegetative body and reproductive body is the internal factor that causes cotton buds to fall off. There are two types of plant imbalance: one is due to thin soil, insufficient fertilizer and water, resulting in short cotton plants, small leaf area, and low photosynthetic output, so tha...
